Horse Digestive Supplement for Gut Support from Stomach to Hindgut

When your horse's behaviour changes… it's rarely "just attitude." The gut is often where the problem begins.

Ulzeraide Plus is a daily horse digestive supplement formulated to support the gastrointestinal system from stomach to hindgut. It contains a mycotoxin binder to aid in the management of the harmful effects of feed-borne mycotoxins while providing daily digestive support for horses.

Your horse's gut health affects far more than digestion. Digestive imbalance can contribute to stomach and hindgut discomfort, increased ulcer risk, and changes in behaviour, comfort and performance.

If your horse suddenly feels tense, girthy, reactive or just "not quite themselves," it may not be attitude.

It may be stomach discomfort.

As the seasons change and grass starts growing rapidly, sugar levels and plant compounds in pasture can disrupt your horse's gut balance. This internal stress can affect the gastrointestinal system and digestive comfort, particularly during periods of travel, competition, stabling, seasonal pasture changes and other everyday challenges.

Ulzeraide Plus is formulated to support the gastrointestinal system from stomach to hindgut, helping maintain digestive comfort so touch becomes comfortable again, saddling isn't a battle, and your horse can relax into their work.

Because gastric ulcers are more common than many horse owners realise.

Studies suggest that up to 50–60% of horses may experience gastric ulcers at some point in their lives—including pleasure horses.

Many horses show subtle signs long before the problem becomes obvious.

Is Your Horse Showing These Signs?

They may need daily digestive support.

🚨 Reacts to saddling or rug changes even when the fit is correct

🚨 Girthy or sensitive during grooming

🚨 Suddenly resistant to bending or going forward

🚨 Increased irritability, tension, bucking or spooking

🚨 Struggles to hold adjustments or feels sore after bodywork

🚨 Soreness through the withers, flank, lumbar region or last rib

🚨 Bloated appearance or signs of gut discomfort

🚨 Reduced appetite or walking away from meals

🚨 Unexplained weight loss or poor condition

🚨 Repeated mild colic episodes

These aren’t “just quirks.”

They’re often early signs of gastric or hindgut discomfort.

Formula update 19th June 2026

At Power Star Nutrition, we are always reviewing our formulas to ensure we provide the best possible support for your horse. As part of this commitment, we have updated the Ulzeraide Plus formula, replacing Aloe Vera with L-Threonine to further support digestive health and gut integrity.

This change has also been influenced by ongoing global supply chain disruptions affecting Aloe Vera availability. To ensure long-term consistency and supply, we have transitioned to L-Threonine as a reliable ingredient moving forward, while maintaining the high-quality gut support Ulzeraide Plus is trusted for.

How Ulzeraide Plus Supports Your Horse

Ulzeraide Plus may be used as a nutritional aid in the general maintenance of gastrointestinal health.

The formula is designed to:

• Help support both foregut and hindgut balance
• Help improve feed intake and fibre digestibility — which may contribute to more efficient feeding and reduced feed costs
• Help horses cope with stress from travel, stabling, competitions and separation anxiety
• Provide a mycotoxin binder to support horses exposed to pasture and feed challenges

By supporting gut health daily, Ulzeraide Plus helps create a more comfortable, resilient digestive system — because prevention is far easier than recovery.

Equine Gastric and Hindgut Ulcers

Several factors contribute to the development of these ulcers. Gastric ulcers in horses are primarily caused by the erosion of the stomach lining due to prolonged exposure to stomach acid. Even under the best management program, a horse can develop gastric ulcers and hindgut ulcers, from the stress of travel, stabling, competitions, separation anxiety, and injuries. Supplementing with a nutritional supplement can help, alongside veterinary medication and diet changes.

Ulzeraide Plus – Calm the Gut. Restore the Comfort

Discover the Synergy of prebiotics, probiotics, herbal extracts, and earth-based nutrients to soothe and protect your horse’s digestive system. Ulzeraide Plus helps support the Gastrointestinal system and contains a mycotoxin binder (Meriden Fusion DYAD) to aid in the management of the harmful effects of feed-borne mycotoxins. ''When light pressure is applied to the acupuncture points marked in red, the horse will twitch, bite, kick, pull faces, or drop back. This can indicate gastric ulcers, grass-related problems, incorrect feeding, or a badly fitting saddle".

How Ulzeraide Plus Supports a Healthy Gut

Ulzeraide Plus actively feeds your horse’s good bacteria! It contains prebiotic components, including Mannan Oligosaccharides (MOS) from yeast cell walls and fenugreek powder. These powerful ingredients nourish beneficial gut bacteria, enhancing the effects of probiotics and creating a balanced, thriving gut ecosystem.

Why this matters:

• Boosts beneficial bacteria: Encourages growth of helpful microbes like Lactobacillus and Bifidobacteria, supporting digestion and gut stability.

• Improves nutrient absorption: A healthier microbiome means your horse can extract more nutrients from feed, improving energy and overall condition.

• Protects gut integrity: Supports the intestinal lining and reduces digestive disturbances, keeping your horse comfortable and performing at their best.

Are You Concerned About The Effects Of Mycotoxins On Your Horses Health?

Ulzeraide Plus contains a mycotoxin binder - Fusion® DYAD* - designed to minimise the negative effects of feed borne mycotoxins.

Features:

✅ Broad-Spectrum Mycotoxin Binder: Fusion® DYAD* helps reduce the risk of aflatoxins, fumonisins, lolitrem B, ergot alkaloids and zearalenone.

✅ Dual-Action Binding: Pure bentonite and mannan oligosaccharides (MOS) work together to provide both physical and chemical binding of a range of mycotoxins.

✅ Ammonia-Binding Properties: Fusion® DYAD also provides excellent ammonia-binding properties alongside selective mycotoxin binding.

Fusion® DYAD* is a broad-spectrum mycotoxin binder that binds to mycotoxins in the feed, preventing them from being absorbed by the animal. The pure form of Bentonite and Mannan Oligosaccharides provide dual-action, physical, and chemical binding of a range of mycotoxins. In addition, it also has excellent ammonia-binding properties and can be used as an anti-caking agent.

Are You Looking For A Probiotic That Can Help Maintain Good Health And Well-being?

Commonly known as direct-fed microbial, probiotics are live microorganisms administered to the horse. The purpose of probiotics is to promote a thriving bacterial environment by increasing the population of beneficial bacteria. Ulzeraide Plus contains LEVUCELL SB and LEVUCELL SB. This probiotic strain, SB, Saccharomyces cerevisiae boulardii, has been used in human medicine for more than 50 years and is well documented with more than 300 available scientific publications. It has also been used in animal feeding for more than 20 years.

Features:

✅ Microbiota Balance: LEVUCELL SB helps create an environment that supports beneficial gut bacteria by consuming oxygen within the digestive tract. It also helps inhibit the activity of microbial toxins such as Clostridium difficile Toxin A and E. coli endotoxin.

✅ Supports Gut Integrity: LEVUCELL SB helps support intestinal integrity by increasing crypt depth and villus height, helping maintain a healthy intestinal barrier.

✅ Supports Natural Defences: Helps support the horse's natural defences through local immune system modulation.

Saccharomyces boulardii is naturally resistant to stomach acid, allowing it to survive transit through the stomach and reach the gut alive where it can provide digestive support.

Levucell® SC

is a live yeast probiotic (Saccharomyces cerevisiae) that supports a healthy and balanced hindgut environment in horses. The hindgut is where fibre from pasture and feed is fermented, producing energy and essential nutrients. When this system is working well, horses are better able to digest fibre efficiently and maintain a stable digestive process, even when diet or conditions change.

One of the key roles of Levucell® SC is helping to stabilise hindgut pH and support beneficial microbial populations. This is especially important for horses exposed to lush pasture, high-starch feeds, or stress from training, travel, or competition. By encouraging the growth of fibre-digesting bacteria and helping reduce the impact of harmful microbes, Levucell® SC supports a more balanced and resilient digestive system.

By improving fibre digestion and supporting gut stability, Levucell® SC can contribute to better nutrient absorption, more consistent manure quality, and overall wellbeing. Many horse owners notice improvements in condition, behaviour, and comfort when the hindgut is functioning optimally, making Levucell® SC a valuable component in supporting long-term digestive health.

Sodium Humic Acid

This revolutionary product features sodium humic acids derived from ancient plant matter, perfect for maintaining cellular balance and optimum digestive health.

Features:

• Humic Acid: Maintains optimum digestive health.
• Improved Nutritive Value of Feed: Stabilizes the intestinal flora and improves protein digestion and calcium and trace element utilization.
• Boost Gut Biology: Increases nutrient uptake and feed utilisation, assisting in optimum digestion.

How it Works:

Humic Acid work to increase the efficiency of all nutrition that enters your horse including supplements, mineral licks, dry feed, and pasture. This natural product boosts gut biology while increasing nutrient uptake and feed utilisation, assisting in optimum digestion. This healthy gut flora is key to overall wellness because it supports immunity and improved digestion.

Fenugreek — Natural Prebiotic Support for Gut Health

Fenugreek seeds are a rich source of galactomannan, a soluble fibre that acts as a natural prebiotic. This fibre resists digestion in the upper gut and slowly ferments in the horse’s hindgut, providing a steady food source for beneficial bacteria such as Bifidobacterium and Lactobacillus.

As these microbes break down the fibre, they produce short-chain fatty acids (SCFAs)—especially butyrate—which nourish the gut-lining cells and support a healthy colon environment. This gentle fermentation process helps maintain a balanced microbiome, improving digestion and reducing the risk of colic, ulcers, and loose manure.

✅ Result: Steadier digestion, improved microbial balance, and more efficient fibre fermentation.

What is L-Threonine?

L-Threonine is an essential amino acid, meaning it must be supplied through the diet because the body cannot produce it on its own. It plays an important role in supporting protein synthesis, tissue repair, and maintaining the health of the digestive tract.

One of L-Threonine’s key roles in gut health is its involvement in the production of mucin—the protective mucus layer that lines the digestive tract. This mucus barrier helps protect the gut lining from irritation, supports intestinal integrity, and plays an important role in maintaining a healthy digestive environment.

In Ulzeraide Plus, L-Threonine has been included to help support gut lining health and overall digestive function. By helping maintain a strong and healthy gut barrier, L-Threonine contributes to ongoing digestive support, especially during times of stress, dietary changes, or increased digestive challenges.

Pazture Mag | Magnesium and B1 for Horses

Magnesium and B1 for horses play an important role in supporting calm behaviour, healthy muscle function, focus, and relaxation.

During periods of grass growth, seasonal change, stress, or fluctuating weather conditions, some horses may become spooky, reactive, muscle sore, or difficult to handle. Pazture Mag provides highly absorbable Magnesium Aspartate and Vitamin B1 (Thiamine) to help support horses throughout the year.

These changes can occur during spring and autumn — but they can also happen at any time of the year depending on pasture conditions, workload, stress levels, and individual nutritional needs.

Pazture Mag is a daily nutritional supplement designed to support calm behaviour, muscle function, focus, and relaxation through highly absorbable magnesium and Vitamin B1 (Thiamine).

Suitable for year-round feeding, Pazture Mag is especially helpful during:

• Spring and autumn grass growth
• Rain after dry spells
• Times of stress or workload
• Horses on lush pasture
• Horses prone to tension, sensitivity, or excitability

Why Feed Magnesium and B1 to Horses?

Power Star Nutrition uses Magnesium Aspartate — commonly referred to as “organic magnesium” — which has a higher biological uptake compared to many other magnesium sources. It is also human grade quality.

Combined with Vitamin B1 (Thiamine), Pazture Mag helps support:

• Calm behaviour
• Healthy muscle function
• Relaxation
• Focus and concentration
• Muscle comfort and recovery
• Horses sensitive to seasonal pasture changes

 

Signs Your Horse May Benefit from Magnesium and B1

Your horse or pony may benefit from daily magnesium and B1 support if they:

• Become spooky or over-reactive when normally calm
• Are sensitive to sound, movement, or touch
• Hate being groomed or rugged
• Show muscle tightness, soreness, tremors, twitching, or cramping
• Lack concentration when ridden
• Have inconsistent behaviour from one ride to the next
• Become more excitable, tense, or difficult to handle
• Fatigue quickly during work
• Struggle to relax after exercise

What Does Thiamine, (Vitamin B1) Do For Horses?

Thiamine is needed for the efficient metabolism of carbohydrates, fats, and proteins. It is also critical for the processing of lactic and pyruvic acids, which contribute to "tying up" and is especially important in competition horses that are often fed large amounts of grain to support athletic ability.

Vitamin B1 may be lacking due to:

• Hard Working Horses
• Horses on high grain diets
• Horses suffering from hindgut acidosis
• Horses suffering from stress

For horses that need extra support from eating green grass and fluctuating weather conditions, Pazture Guarde is a more heavy-duty supplement fed daily. Pazture Mag can be fed with Ulzeraide Plus for grass and feed challenges.

Why feed Magnesium to Horses?

Magnesium plays an important part in nerve and muscle function. Horses who are deficient show signs of nervousness, and excitability, are jumpy, and have tight sore backs which are not related to saddle fit. They have muscle tremors and skin hypersensitivity. A magnesium-deficient horse is likely to have a poor tolerance to work, fatigue quickly, and be prone to tying up. They build up lactic acid more quickly which is why magnesium deficient horses sometimes have behavior problems. They fatigue more quickly after work and don't recover as well. When a horse gets excited, its body uses magnesium to calm down and relax. The lower the magnesium level, the lower the threshold for new stress. Magnesium deficient horses can start calm during exercise. As the session progresses, they become spookier and more stressed.

What Causes Magnesium Deficiency?

Magnesium tends to be deficient in Spring grasses due to the fast rate of growth. This is part of the reason why horses exhibit signs of Spring Flush (silly behavior), as magnesium deficiency commonly results in behavioral problems in horses.  

Horse Vitamin & Mineral Supplement for Healthy Hooves, Skin & Coat

Restore Essential Vitamins & Minerals Missing from Your Horse's Diet

 

Is Your Horse Struggling with Poor Hoof Quality, Mud Fever, or Skin Conditions?

Are your horse's hooves still cracking and brittle even though you take good care of them? Did you know, low levels of zinc and copper could be the problem? Learn how Essentials Formula 1, with selenium, can transform weak, brittle hooves into strong, resilient foundations for your horse in 6-9 months. Feeding Essentials Formula 1, daily can help prevent skin conditions like mud fever and rain scald, especially during wet conditions. This super equine vitamin, mineral, amino acid, and hoof supplement all rolled into one,  promotes a shiny coat, healthy hooves, and topline. This formula has high levels of Biotin, plus amino acids,  L-Lysine and DL-Methionine and L-Threonine. It has the correct ratio of Zinc to Copper for maximum absorption.

Signs Your Horse May Be Missing Essential Vitamins & Minerals

Then list things like:

• Poor hoof quality
• Cracking hooves
• Slow hoof growth
• Mud fever
• Rain scald
• Poor coat
• Lack of topline
• Faded coat
• Poor condition

Specifically formulated for NZ conditions and Soil types

Essentials Formula 1, provides essential nutrients lacking in many feed crops, pastures, and soil. It has no added iron, making it the perfect supplement for horses and ponies grazing on NZ pasture and drinking bore water with high iron content. Essentials Formula 1 is one of the best copper and zinc supplements for horses. Designed for horses and ponies not receiving premix feeds, or below recommended daily rate. It can also be fed when a very small amount of premix feed is fed, and daily recommended vitamin and mineral requirements are not being met. The level of selenium will generally keep the average horse or pony at current selenium levels unless the soil is fertilized with selenium prills or the pasture is high in selenium. Getting your horse's blood tested for selenium yearly is highly recommended.

Essentials Formula 1, Selenium Free is recommended when:

• Your horse or pony receives a blood test showing high selenium levels but still requires a vitamin and mineral supplement to maintain health with no selenium added.
• Is being supplemented with selenium from your veterinarian or other supplements?
• Grazing on a property that has high levels of selenium in the soil and pasture.

Equine Minerals: The Importance of Zinc, Copper, and an Iron-Free Formulation

New Zealand's pasture, hay, and feed crops have high iron levels which can reduce the availability of zinc and copper. The most common mineral imbalance in hay is too much iron combined with low zinc and copper levels. A high iron concentration can interfere with both zinc and copper absorption, making already low levels of these minerals even less available to your horse. Until recently, the veterinary industry has viewed iron toxicity in equines mainly as an acute condition—the result of overdosing on iron-containing supplements. However, researchers have found that equines exposed to high iron levels in water, grass, or hay over a prolonged period can accumulate the mineral in their livers, resulting in chronic iron overload. Black-skinned horses which include greys need more copper and zinc than others. Bays and chestnuts will look washed out with lighter colors than normal coats, and the blacks will have a definite reddish look. Horses need copper in their diets to properly utilize iron and to develop healthy connective tissue. It is also important for horses with allergies. It can lower the concentration of histamine in the body. Copper also helps to keep the central nervous system running correctly. In adult horses, a deficiency of copper and zinc in the diet may cause limb deformities, thinning of the bones, swelling of the joints, blood vessel weakness, connective tissue weakness, saggy skin, and a lowered immune system.  Copper is the main mineral for the body to produce T cells. It is also important for bone integrity, heart health, skin pigmentation, and to prevent premature graying. Horses showing signs of low iron levels can be supplemented according to veterinary instructions. When copper deficiency occurs, iron levels fall too short, and anemia can develop.

Avoid Added Iron

Avoid vitamin and mineral supplements for horses that contain added iron as an ingredient. Horses typically obtain more than enough iron from their diet, and excess intake could have negative health consequences. Products with added iron will have one of the following ingredients listed on the label:

• iron oxide
• ferrous furmate
• ferrous sulfate
• ferrous gluconate

Magnesium

It does not contain Magnesium. Magnesium requirements are individual and a different magnesium product like Pazture Guarde or Pazture Mag can be added separately.

Vitamin E

Most grazing horses receive natural vitamin E from fresh pasture. Essentials Formula 1 is therefore formulated to complement pasture diets by supplying key trace minerals such as zinc, copper and selenium that are often low or poorly absorbed in New Zealand soils.” Vitamin E is not included in Essentials Formula 1 mineral/vitamin mixes because it oxidizes very quickly when added to feeds or multi-ingredient supplements. For this reason, it is more effective to supplement Vitamin E separately to ensure its benefits are fully realised. “Vitamin E is naturally supplied when horses consume fresh green pasture.”

NZ Natural Zeolite

Essentials Formula 1 and 2 contain NZ natural Zeolite in the form of Optimate, an ACVM-registered toxin binder. This is a highly bioavailable natural form of silica that supports bone and connective tissue health. Performance horses and senior horses may especially benefit from Zeolite.

Are you looking for a way to improve your horse's hoof health?

Essentials Formula contains high levels of  Biotin. Each 22.5-gram scoop contains 15mg of biotin. This sulphur-containing B vitamin is essential for healthy hoof growth and plays a role in hoof horn quality and hoof wall strength. Biotin supplementation has become increasingly popular in recent years, as it can help correct biotin deficiencies, improve hoof hardness, and promote overall hoof health.

Features:

🐎 Essential for healthy hoof growth: Biotin is an essential coenzyme in the metabolism of carbohydrates, protein and fat, enabling support of growth, performance work and reproduction. 💪 Improves hoof hardness: Biotin is used in supplements to improve the quality of the horse’s hoof and is also beneficial to the coat. 🦄 Promotes overall hoof health: By using a biotin supplement in your horse’s feed, it can help promote strong, healthy hoof horn growth.

How it works:

Biotin should be fed to horses needing to improve poor hoof horn and develop healthy hooves. It acts as an essential coenzyme in the metabolism of carbohydrates, protein, and fat and so enables support of growth, performance work, and reproduction. Biotin is particularly important for normal thyroid and adrenal gland function.
